Abstract
A material dispensing device includes a material storage unit that stores a material therein and has an outlet portion at a lower portion thereof, and a dispensing unit that dispenses the material dispensed from the outlet portion to an outside with at least a part of the material being plasticized. The material dispensing device includes a remaining amount detection unit that detects a remaining amount of the material stored in the material storage unit from above the material storage unit. A three-dimensional shaping device includes the material dispensing device that dispenses a material for shaping, and a stage on which the material dispensed from the material dispensing device is stacked.
Claims7
A three-dimensional shaping device comprising:
- a material dispensing device configured to dispense a material for shaping from a dispensing unit;
- and
- a stage configured to receive the material for shaping dispensed from the dispensing unit, wherein the material dispensing device comprises
- a material storage unit configured to store a material therein and having an outlet portion at a lower portion thereof;
- a dispensing unit configured to dispense the material supplied from the outlet portion to an outside with at least a part of the material being plasticized;
- a remaining amount detection unit configured to detect a remaining amount of the material stored in the material storage unit from above the material storage unit;
- a first movement unit configured to move the material storage unit and the dispensing unit in a first direction perpendicular to the stage;
- a second movement unit configured to individually move the material storage unit in the first direction;
- a third movement unit configured to individually move the dispensing unit in the first direction;
- and
- a control unit configured to:
- control movement operations of the first movement unit, the second movement unit, and the third movement unit, and
- during shaping, the control unit causes the third movement unit to move the dispensing unit, and causes a dispensing port of a nozzle included in the dispensing unit to be closer to the stage than during a period other than during the shaping.
